Research Interest:

My laboratory focuses on the development of synthetic delivery systems for use in nucleic acids-based therapies (e.g., gene, siRNA, antisense, aptamers).  Our most recent work focuses on understanding the immune responses elicited after intravenous administration of different nanoparticle formulations. Ultimately, the goal of these studies is to develop lipid-based delivery systems that elicit minimal immune responses upon repeat administration and preferentially target tumors.

Another major focus in the lab is the use of exosomes and the exosomal pathway for drug delivery. We recently began a project in which exosomes from cow milk are used to orally administer chemotherapeutics that typically require intravenous infusion. Studies on our delivery systems include biophysical characterization, pharmaceutical optimization, cell culture assessment, and ultimately testing in animal models.

In addition, we have conducted many studies on the stability of delivery systems during physical stresses, e.g., freezing and drying. The goal of this research is to develop formulations for therapeutic use that will be stable on a pharmaceutically-relevant timescale (~ 2 years). While many of our previous studies have involved acute stresses, our more recent work has focused on prolonged storage of polynucleotides and delivery systems in the dried state.

Our laboratory also conducts traditional pharmaceutical research involving the formulation and delivery of small molecule therapeutics. This latter research is very translational in nature, and our efforts have led to a commercially-available topical formulation (Difinsa53®) used to protect skin during radiation therapy.
